libssh 代码问题漏洞

libssh is a C development package from the libssh organization for accessing SSH services that can perform remote commands, file transfers, and also provide a secure transport channel for remote programs. A code issue vulnerability exists in libssh that stems from a possible null pointer...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference via the calculation of the session ID during the key exchange process. An attacker can cause a crash of SSH clients or servers by triggering an allocation failure in cryptographic functions. Remediation Upgrade...

CVE-2025-44647

In TRENDnet TEW-WLC100P 2.03b03, the idontcareaboutsecurityanduseaggressivemodepsk option is enabled in the strongSwan configuration file, so that IKE Responders are allowed to use IKEv1 Aggressive Mode with Pre-Shared Keys to conduct offline attacks on the openly transmitted hash of the PSK...

OESA-2025-1864 python-cryptography security update

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Security Fixes: A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lea...

Hybrid Quantum Security for IPsec

Quantum Key Distribution QKD offers information-theoretic security against quantum computing threats, but integrating QKD into existing security protocols remains an unsolved challenge due to fundamental mismatches between pre-distributed quantum keys and computational key exchange paradigms. Thi...

On Key Exchange Protocol Based on Two-Side Multiplication Action

We present a cryptanalysis of a key exchange protocol based on the digital semiring. For this purpose, we find the maximal solution of a linear system over such semiring, and use the properties of circulant matrix to demonstrate that the protocol is vulnerable. Specifically, we provide an efficie...

Low-order Point Validation Failure

github.com/cloudflare/circl is vulnerable to low-order point validation failure. The vulnerability is due to the failure to validate user-supplied low-order points during the Diffie-Hellman key exchange, which can allow attackers to force the identity point and compromise session security...

Important: amazon-ssm-agent

Issue Overview: SSH servers which implement file transfer protocols are vulnerable to a denial of service attack from clients which complete the key exchange slowly, or not at all, causing pending content to be read into memory, but never transmitted. CVE-2025-22869 Affected Packages:...

GHSA-2X5J-VHC8-9CWM CIRCL-Fourq: Missing and wrong validation can lead to incorrect results

Impact The CIRCL implementation of FourQ fails to validate user-supplied low-order points during Diffie-Hellman key exchange, potentially allowing attackers to force the identity point and compromise session security. Moreover, there is an incorrect point validation in ScalarMult can lead to...
